The present invention relates to a herbicidal composition whichcomprises at least one herbicide A selected from glyphosate, glufosinateand their salts. The composition is particularly useful for preplantburndown.

Burndown, i.e. the complete removal of weeds from the soil byapplication of herbicides prior to planting or emergence of a crop, isan important tool of modern weed management. Weeds present at plantingwill generally grow much quicker than crop plants and thus compete veryearly in the growing season thereby damaging the crop plants andreducing crop yield. Thus, it is desirable to plant the crop in aweed-free seed bed or to assure that essentially no weeds are presentwhen the crop emerges.

Glyphosate and its salts are non-selective systemic herbicides having agood post-emergence activity against numerous grass weeds. So far,glyphosate is one of the most commonly used burndown herbicides.Likewise, glufosinate and its salts are non-selective systemicherbicides having a good post-emergence activity against numerous grassweeds and thus can be used in burndown programs. However, soloapplication of glyphosate or glufosinate often yields unsatisfactoryweed control, and several applications and/or high dosage rates areoften required. Moreover, the effectiveness of glyphosate andglufosinate against difficult-to-control broadleaf species (hereinafterbroadleaves) and rhizomatous grasses is poor. Therefore, it isfrequently recommended to apply glyphosate or glufosinate in combinationwith at least one second herbicide, such as 2,4-D, dicamba, triazinessuch as atrazine or metribuzin, chloroacetanilides such as metholachloror dimethenamid (including dimethenamid-P), linuron and/orpendimethalin. However, the effectiveness of such combinations is oftennot satisfactory and high application rates are still required toachieve an acceptable control of grass weeds and broadleaves. Moreover,the reliability of such combinations depends strongly on the weatheringconditions and certain difficult to control weed species may escape. Inaddition, the herbicidal activity of these compositions persists onlyfor a short time, which allows effective burndown only within a smalltimeframe prior to planting a crop. Moreover, the persistence of theherbicidal activity strongly depends upon the weathering conditions.

U.S. Pat. No. 6,413,909 suggests a composition comprising ametryn,atrazin and paraquat for burndown treatment. Paraquat, however is rathertoxic to mammals and thus its use is restricted by legal regulations.

US 2005/0256004 discloses a herbicidal composition comprising anisoxazoline derivatives and at least one further herbicide. Neither thecombination of glyphosate and pyroxasulfone nor the use of suchcompositions in a burndown program have been described therein.

Thus, it is an object of the present invention to provide a herbicidalcomposition, which allows efficient and reliable control of grass andbroadleaf weeds in a burndown program. Moreover, the persistence of theherbicidal activity of the composition should be sufficiently long inorder to achieve control of the weeds over a sufficient long time periodthus allowing a more flexible application. The composition should alsohave a low toxicity to humans or other mammals. The compositions shouldalso show an accelerated action on harmful plants, i.e. they shouldeffect damaging of the harmful plants more quickly in comparison withapplication of the individual herbicides.

These and further objects are achieved by the compositions describedhereinafter.

Therefore the present invention relates to a herbicidal compositioncomprising:

-   a) at least one herbicide A selected from glyphosate, glufosinate    and their salts, and-   b) a herbicide B which is    3-[5-(difluoromethoxy)-1-methyl-3-(trifluoromethyl)pyrazol-4-ylmethylsulfonyl]-4,5-dihydro-5,5-dimethyl-1,2-oxazole    [common name: pyroxasulfone].

It has been proven particular advantageous to combine the herbicides Aand B with at least one further herbicide C, which is selected from

-   C.1 herbicides of the group of acetolactate synthase inhibitors (ALS    inhibitors),-   C.2 herbicides of the group of protoporphyrinogen oxidase inhibitors    (PPO inhibitors),-   C.3 herbicides of the group of auxins,-   C.4 herbicides of the group of 4-hydroxyphenylpyruvate dioxygenase    inhibitors (HPPD inhibitors),-   C.5 herbicides of the group of phytoene desaturase inhibitors (PDS    inhibitors),-   C.6 herbicides of the group of photosystem II inhibitors (PSII    inhibitors),-   C.7 herbicides of the group of microtubulin inhibitors, and-   C.8 herbicides of the group of inhibitors of the synthesis of very    long chain fatty acids (VLCFA inhibitors).

Therefore, the present invention relates in particular to a herbicidalcomposition comprising:

-   a) at least one herbicide A selected from glyphosate, glufosinate    and their salts,-   b) a herbicide B which is    3-[5-(difluoromethoxy)-1-methyl-3-(trifluoromethyl)pyrazol-4-ylmethylsulfonyl]-4,5-dihydro-5,5-dimethyl-1,2-oxazole    [common name: pyroxasulfone], and-   c) at least one further herbicide C, which is selected from the    herbicide groups C.1 to C.8 as defined herein.

The invention furthermore relates to the use of a composition as definedherein for controlling undesirable vegetation. When using thecompositions of the invention for this purpose the at least oneherbicide A and the herbicide B and optionally C can be appliedsimultaneously or in succession, where undesirable vegetation may occur.

The invention furthermore relates to the use of a composition as definedherein for controlling undesirable vegetation for burndown, i.e. forcontrolling undesirable vegetation in a locus, e.g. a field, where cropswill be planted, before planting or emergence of the crop.

The invention furthermore relates to the use of a composition as definedherein for controlling undesirable vegetation in crops which, by geneticengineering or by breeding, are resistant to one or more herbicidesand/or pathogens such as plant-pathogenous fungi, and/or to attack byinsects; preferably resistant to glyphosate or glufosinate, andoptionally resistant to the one or more optional herbicides C.

The invention furthermore relates to a method for controllingundesirable vegetation, which comprises applying an herbicidalcomposition according to the present invention to the undesirablevegetation. Application can be done before, during and/or after,preferably during and/or after, the emergence of the undesirablevegetation. The at least one herbicide A, the herbicide B and theoptional at least one herbicide C can be applied simultaneously or insuccession.

The invention in particular relates to a method for controllingundesirable vegetation in crops, which comprises applying

-   a) at least one herbicide A selected from glyphosate, glufosinate    and their salts, and optionally-   b) a herbicide B which is    3-[5-(difluoromethoxy)-1-methyl-3-(trifluoromethyl)pyrazol-4-ylmethylsulfonyl]-4,5-dihydro-5,5-dimethyl-1,2-oxazole,-   c) one or more herbicides C, selected from the herbicides of the    groups C.1 to C.8 as defined herein,    to a locus of planted crops where undesirable vegetation occurs or    might occur or to a locus where crops will be planted before    planting or emergence of the crop.

In the methods of the present invention it is immaterial whether the atleast one herbicide A and the herbicide B and the one or more optionalherbicides C are formulated jointly or separately and applied jointly orseparately, and, in the case of separate application, in which order theapplication takes place. It is only necessary, that the at least oneherbicide A and the herbicide B and the one or more optional herbicidesC are applied in a time frame, which allows simultaneous action of theactive ingredients on the undesirable plants.

The invention also relates to an herbicide formulation, which comprisesa herbicidally active composition as defined herein and at least onecarrier material, including liquid and/or solid carrier materials.

The compositions of the present invention have several advantages oversolo application of either glyphosate/glufosinate or pyroxasulfone. Thecomposition of the present invention show enhanced herbicide action incomparison with the herbicide action of solo action glyphosate orpyroxasulfone against undesirable vegetation, in particular againstdifficult to control species such as Alopecurus myosuroides, Avenafatua, Bromus spec., Echinocloa spec. Ipomea spec., Lolium spec.,Phalaris spec., Setaria spec., Digitaria spec., Brachiaria spec.,Amaranthus spec., Chenopodium spec., Abutilon theophrasti, Galiumaparine, Veronica spec., or Solanum spec. Moreover, the compositions ofthe invention show a persistent herbicidal activity, even underdifficult weathering conditions, which allows a more flexibleapplication in burndown applications and minimizes the risk of weedsescaping. The compositions are generally non-toxic or of low toxicityagainst mammals. Apart form that, the compositions of the presentinvention show superior crop compatibility with certain conventionalcrop plants and with herbicide tolerant crop plants, i.e. their use inthese crops leads to a reduced damage of the crop plants and/or does notresult in increased damage of the crop plants. Thus, the compositions ofthe invention can also be applied after the emergence of the cropplants. The compositions of the present invention may also show anaccelerated action on harmful plants, i.e. they may effect damage of theharmful plants more quickly in comparison with solo application of theindividual herbicides.

Although, these advantages may be achieved by combining glyphosateand/or glufosinate with pyroxasulfone, it is particularly beneficial tofurther combine these herbicides A and B with at least one furtherherbicide C of the herbicide groups C.1 to C.8. These compositions showenhanced herbicide action in comparison with the herbicide action ofcombinations of herbicides A+B against undesirable vegetation, inparticular against difficult to control species, and/or show superiorcrop compatibility with certain conventional crop plants and withherbicide tolerant crop plants, i.e. their use in these crops leads to areduced damage of the crop plants and/or does not result in increaseddamage of the crop plants. Apart from that, these compositions may alsoshow an accelerated action on harmful plants, i.e. they may effectdamage of the harmful plants more quickly in comparison with soloapplication of the individual herbicides.

continuation 2 of table 1: Mixtures 659 to 1044: These mixturescorrespond to mixtures 273 to 658, wherein glyphosate has been replacedby gluphosinate or a salt thereof. (herbicide A is glyphosate, herbicideB is pyroxasulfone)

The compositions of the invention may also comprise, as a component d),one or more safeners. Safeners, also termed as herbicide safeners areorganic compounds which in some cases lead to better crop plantcompatibility when applied jointly with specifically acting herbicides.Some safeners are themselves herbicidally active. In these cases, thesafeners act as antidote or antagonist in the crop plants and thusreduce or even prevent damage to the crop plants. However, in thecompositions of the present invention, safeners are generally notrequired. Therefore, a preferred embodiment of the invention relates tocompositions which contain no safener or virtually no safener (i.e. lessthan 1% by weight, based on the total amount of herbicide A andherbicide B).

Suitable safeners, which can be used in the compositions according tothe present invention are known in the art, e.g. from

A preferred embodiment of the invention relates to compositions whichcontain no safener or virtually no safener (i.e. less than 1% by weight,based on the total amount of the at least one herbicide A and herbicideB and optionally herbicide C) is applied.

The compositions of the present invention are suitable for controlling alarge number of harmful plants, including monocotyledonous weeds, inparticular annual weeds such as gramineous weeds (grasses) includingEchinochloa species such as barnyardgrass (Echinochloa crusgalli var.crus-galli), Digitaria species such as crabgrass (Digitariasanguinalis), Setaria species such as green foxtail (Setaria viridis)and giant foxtail (Setaria faberii), Sorghum species such asjohnsongrass (Sorghum halepense Pers.), Avena species such as wild oats(Avena fatua), Cenchrus species such as Cenchrus echinatus, Bromusspecies, Lolium species, Phalaris species, Eriochloa species, Panicumspecies, Brachiaria species, annual bluegrass (Poa annua), blackgrass(Alopecurus myosuroides), Aegilops cylindrica, Agropyron repens, Aperaspica-venti, Eleusine indica, Cynodon dactylon and the like.

The compositions of the present invention are also suitable forcontrolling a large number of dicotyledonous weeds, in particular broadleaf weeds including Polygonum species such as wild buckwheat (Polygonumconvolvolus), Amaranthus species such as pigweed (Amaranthusretroflexus), Chenopodium species such as common lambsquarters(Chenopodium album L.), Sida species such as prickly sida (Sida spinosaL.), Ambrosia species such as common ragweed (Ambrosia artemisiifolia),Acanthospermum species, Anthemis species, Atriplex species, Cirsiumspecies, Convolvulus species, Conyza species, Cassia species, Commelinaspecies, Datura species, Euphorbia species, Geranium species, Galinsogaspecies, morningglory (Ipomoea species), Lamium species, Malva species,Matricaria species, Sysimbrium species, Solanum species, Xanthiumspecies, Veronica species, Viola species, common chickweed (Stellariamedia), velvetleaf (Abutilon theophrasti), Hemp sesbania (Sesbaniaexaltata Cory), Anoda cristata, Bidens pilosa, Brassica kaber, Capsellabursa-pastoris, Centaurea cyanus, Galeopsis tetrahit, Galium aparine,Helianthus annuus, Desmodium tortuosum, Kochia scoparia, Mercurialisannua, Myosotis arvensis, Papaver rhoeas, Raphanus raphanistrum, Salsolakali, Sinapis arvensis, Sonchus arvensis, Thlaspi arvense, Tagetesminuta, Richardia brasiliensis, and the like.

The compositions of the present invention are also suitable forcontrolling a large number of annual and perennial sedge weeds includingcyperus species such as purple nutsedge (Cyperus rotundus L.), yellownutsedge (Cyperus esculentus L.), hime-kugu (Cyperus brevifolius H.),sedge weed (Cyperus microiria Steud), rice flatsedge (Cyperus iria L.),and the like.

The compositions of the present invention are particularly useful inso-called burndown programs, in particular preplant burndown programs.i.e. the compositions of the invention are applied to a locus wherecrops will be planted before planting or emergence of the crop.

Therefore, the present invention also relates to a method for burndowntreatment of undesirable vegetation in crops, comprising applying

-   a) at least one herbicide A selected from glyphosate, glufosinate    and their salts, and-   b) a herbicide B which is    3-[5-(difluoromethoxy)-1-methyl-3-(trifluoromethyl)pyrazol-4-ylmethylsulfonyl]-4,5-dihydro-5,5-dimethyl-1,2-oxazole,    to a locus where crops will be planted before planting or emergence    of the crop.

In the burndown treatment of the present invention, additionally atleast one further herbicide C from the groups C.1 to C.8 as definedabove can be applied together with the herbicides A and B. The term “toapply together” includes simultaneous and successive application.Likewise, applying the composition does not necessarily mean that thecompounds A, B and optionally C must be applied as a single formulationor as a tank mix. Rather, the composition includes separate formulationsof herbicides A and B and optionally C, which can be applied as a singletank-mix or via separate application means. In any case, the at leastone herbicide A, the herbicide B and the one or more optional herbicidesC can be applied simultaneously or in succession.

However, it is also possible to apply the herbicide C in the burndowntreatment after seeding or even after emergence of the crop.

Though possible, it is not necessary to formulate the herbicides A, Band optionally C in a single formulation. Usually the herbicides A and Band optionally C are combined as a tank-mix prior to application. It ishowever also possible to provide a premix of the herbicide B and theoptional herbicide C and to combine this premix with the at least oneherbicide A.

The compositions of the present invention can be applied in conventionalmanner by using techniques as skilled person is familiar with. Suitabletechniques include spraying, atomizing, dusting, spreading or watering.The type of application depends on the intended purpose in a well knownmanner; in any case, they should ensure the finest possible distributionof the active ingredients according to the invention.

The compositions are applied to locus mainly by spraying, in particularfoliar spraying of an aqueous dilution of the active ingredients of thecomposition. Application can be carried out by customary sprayingtechniques using, for example, water as carrier and spray liquor ratesof from about 10 to 2000 I/ha or 50 to 1000 I/ha (for example from 100to 500 I/ha). Application of the herbicidal compositions by thelow-volume and the ultra-low-volume method is possible, as is theirapplication in the form of microgranules.

If the active ingredients are less well tolerated by certain cropplants, application techniques may be used in which the herbicidalcompositions are sprayed, with the aid of the spray apparatus, in such away that they come into as little contact, if any, with the leaves ofthe sensitive crop plants while reaching the leaves of undesirableplants which grow underneath, or the bare soil (post-directed, lay-by).

The compositions can be applied pre- or post-emergence, i.e. before,during and/or after emergence of the undesirable plants.

When the compositions are used in burndown programs, they can be appliedprior to seeding (planting) or after seeding (or planting) of the cropplants but before the emergence of the crop plants. The compositions arepreferably applied prior to seeding of the crop plants. For burndown,the compositions will generally be applied a date up to 9 month,frequently up to 6 month, preferably up to 4 month prior to planting thecrop. The burndown application can be done at a date up to 1 day priorto emergence of the crop plant and is preferably done at a date prior toseeding/planting of the crop plant, preferably at a date of at least oneday, preferably at least 2 days and in particular at least one 4 daysprior to planting or from 6 month to 1 day prior emergence, inparticular from 4 month to 2 days prior emergence and more preferablyfrom 4 month to 4 days prior emergence. It is, of course, possible torepeat the burndown application once or more, e.g. once, twice, threetimes, four times or five times within that time frame.

In the burndown treatment according to the present invention, the atleast one herbicide A and the herbicide B are applied to the field ofthe crop plants prior to the emergence of the crop plants, in particularprior to seeding within the above time frame. In a specific embodimentof this burndown treatment, the one or more herbicides C are alsoapplied within this time frame. In this specific embodiment is alsopossible to additionally apply the one or more herbicides C andoptionally further pyroxasulfone after the planting or seeding or evenafter emergence of the crop, preferably at a date until 12 weeks afteremergence of the crop. In another specific embodiment of this burndowntreatment, the one or more herbicides C and optionally furtherpyroxasulfone are only applied after the planting or seeding or evenafter emergence of the crop, preferably at a date until 12 weeks afteremergence of the crop.

It is a particular benefit of the compositions according to theinvention that they have a very good post-emergence herbicide activity,i.e. they show a good herbicidal activity against emerged undesirableplants. Thus, in a preferred embodiment of invention, the compositionsare applied post-emergence, i.e. during and/or after, the emergence ofthe undesirable plants. It is particularly advantageous to apply themixtures according to the invention post emergent when the undesirableplant starts with leaf development up to flowering. The compositions areparticularly useful for controlling undesirable vegetation which hasalready developed to a state, which is difficult to control withconventional brundown compositions, i.e. when the individual weed istaller than 10 cm (4 inches) or even taller than 15 cm (6 inches) and/orfor heavy weed populations.

In the case of a post-emergence treatment of the plants, the herbicidalmixtures or compositions according to the invention are preferablyapplied by foliar application.

Application may be effected, for example, by usual spraying techniqueswith water as the carrier, using amounts of spray mixture of usuallyfrom 10 to 2000 I/ha, in particular 50 to 1000 I/ha.

The required application rate of the composition of the pure activecompounds, i.e. of pyroxasulfone, herbicide A and optionally herbicide Cdepends on the density of the undesired vegetation, on the developmentstage of the plants, on the climatic conditions of the location wherethe composition is used and on the application method.

The compositions according to the present invention are suitable forcombating/controlling common harmful plants in fields, where usefulplants shall be planted (i.e. in crops). The compositions of the presentinvention are generally suitable for burndown of undesired vegetation infields of the following crops:

-   -   Grain crops, including e.g.        -   cereals (small grain crops) such as wheat (Triticum            aestivum) and wheat like crops such as durum (T. durum),            einkorn (T. monococcum), emmer (T. dicoccon) and spelt (T.            spelta), rye (Secale cereale), triticale (Tritiosecale),            barley (Hordeum vulgare);        -   maize (corn; Zea mays);        -   sorghum (e.g. Sorghum bicolour);        -   rice (Oryza spp. such as Oryza sativa and Oryza glaberrima);            and        -   sugar cane;    -   Legumes (Fabaceae), including e.g. soybeans (Glycine max),        peanuts (Arachis hypogaea and pulse crops such as peas including        Pisum sativum, pigeon pea and cowpea, beans including broad        beans (Vicia faba), Vigna spp., and Phaseolus spp. and lentils        (lens culinanis var.);    -   brassicaceae, including e.g. canola (Brassica napus), oilseed        rape (OSR, Brassica napus), cabbage (B. oleracea var.), mustard        such as B. juncea, B. campestris, B. narinosa, B. nigra and B.        tournefortii; and turnip (Brassica raga var.);    -   other broadleaf crops including e.g. sunflower, cotton, flax,        linseed, sugarbeet, potato and tomato;    -   TNV-crops (TNV: trees, nuts and vine) including e.g. grapes,        citrus, pomefruit, e.g. apple and pear, coffee, pistachio and        oilpalm, stonefruit, e.g. peach, almond, walnut, olive, cherry,        plum and apricot;    -   turf, pasture and rangeland;    -   onion and garlic;    -   bulb ornamentals such as tulips and narcissus;    -   conifers and deciduous trees such as pinus, fir, oak, maple,        dogwood, hawthorne, crabapple, and rhamnus (buckthorn); and        garden ornamentals such as roses, petunia, marigold and        snapdragon.

The compositions of the present invention are in particular suitable forburndown of undesired vegetation in fields of the following crop plants:small grain crops such as wheat, barley, rye, triticale and durum, rice,maize (corn), sugarcane, sorghum, soybean, pulse crops such as pea, beanand lentils, peanut, sunflower, sugarbeet, potato, cotton, brassicacrops, such as oilseed rape, canola, mustard, cabbage and turnip, turf,pasture, rangeland, grapes, pomefruit, such as apple and pear,stonefruit, such as peach, almond, walnut, pecans, olive, cherry, plumand apricot, citrus, coffee, pistachio, garden ornamentals, such asroses, petunia, marigold, snap dragon, bulb ornamentals such as tulipsand narcissus, conifers and deciduous trees such as pinus, fir, oak,maple, dogwood, hawthorne, crabapple and rhamnus.

The compositions of the present invention are most suitable for burndownof undesired vegetation in fields of the following crop plants: smallgrain crops such as wheat, barley, rye, triticale and durum, rice,maize, sugarcane, soybean, pulse crops such as pea, bean and lentils,peanut, sunflower, cotton, brassica crops, such as oilseed rape, canola,turf, pasture, rangeland, grapes, stonefruit, such as peach, almond,walnut, pecans, olive, cherry, plum and apricot, citrus and pistachio.

If not stated otherwise, the compositions of the invention are suitablefor application in fields of any variety of the aforementioned cropplants.

The compositions according to the invention can also be used in cropplants which are resistant to one or more herbicides owing to geneticengineering or breeding, which are resistant to one or more pathogenssuch as plant pathogenous fungi owing to genetic engineering orbreeding, or which are resistant to attack by insects owing to geneticengineering or breeding. Suitable are for example crop plants,preferably corn, wheat, sunflower, rice, canola, oilseed rape, soybeans,cotton and sugarcane, which are resistant or tolerant to glyphosateand/or glufosinate, crop plants which are resistant or tolerant toauxins such as dicamba, crop plants which are resistant or tolerant toHPPD inhibitors, crop plants which are resistant or tolerant to ALSinhibitors such as crop plants which are resistant or tolerant toimidazolinones, crop plants which are resistant or tolerant to PPOinhibitors or crop plants which, owing to introduction of the gene forBt toxin by genetic modification, are resistant to attack by certaininsects.

In a particular a specific embodiment, the compositions of the presentinventions are used for controlling undesirable vegetation to cropplants, which are tolerant to herbicides, in particular in crop plantsthat are resistant or tolerant to glyphosate and/or glufosinate andwhich are stacked with further resistance or tolerance against at leastone further herbicide, in particular at least one of the followingherbicides: auxins such as dicamba, HPPD inhibitors, ALS inhibitors, inparticular imidazolinones, PPO inhibitors.

In these herbicide resistant or tolerant crops, the compositions of thepresent invention can be used both for burndown and for control ofundesired vegetation after emergence of the crops. Therefor, aparticular embodiment of the invention relates to a method forcontrolling undesirable vegetation in herbicide resistant or tolerantcrops, in particular in crop plants which are resistant or tolerant toglyphosate and/or glufosinate and which are optionally stacked withfurther resistance or tolerance against at least one further herbicide,in particular at least one of the following herbicides: auxins such asdicamba, HPPD inhibitors, ALS inhibitors, in particular imidazolinones,PPO inhibitors. In this particular embodiment, the compositions can beused for burndown but also for the control of undesirable vegetationafter the crop plants.

In this particular method of the invention, the composition of theinvention can be applied at least once prior to planting or emergence ofthe herbicide resistant or tolerant crop plant to achieve effectiveburndown of the undesirable vegetation and the composition can also beapplied after emergence of the herbicide resistant or tolerant cropplants.

If the compositions of the present invention are used in crop plants,i.e. if they are applied in fields of the crop plants after emergence ofthe crops, application methods and application rates as described forburndown can be applied. If the active ingredients are less welltolerated by certain crop plants, application techniques may be used inwhich the herbicidal compositions are sprayed, with the aid of the sprayapparatus, in such a way that they come into as little contact, if any,with the leaves of the sensitive crop plants while reaching the leavesof undesirable plants which grow underneath, or the bare soil(post-directed, lay-by). However such methods are generally notnecessary and the compositions can be simply applied over the top (OTT).

For example, a composition comprising glyphosate and/or glufosinate oran agriculturally acceptable salt thereof, pyroxasulfone and animidazolinone herbicide is particularly useful for burndown in fields,where a glyphosate tolerant crop having imidazolinone tolerance shall beplanted such as maize, canola, wheat, soybeans or sunflower, all ofwhich having glyphosate and/or glufosinate tolerance and imidazolinonetolerance. Such compositions are also particularly useful for burndownin fields where sugarcane shall be planted, the sugarcane beingconventional sugarcane or sugarcane being tolerant to glyphosate orglufosinate optionally stacked with tolerance against imidazolinones.These compositions can also used for controlling undesirable vegetationin crops having glyphosate and/or glufosinate resistance stacked withimidazolinone resistance after emergence of the crop.

For example, a composition comprising glyphosate and/or glufosinate oran agriculturally acceptable salt thereof, pyroxasulfone and an auxinherbicide is particularly useful for burndown in fields both ofconventional crops such as maize, canola, wheat, soybeans, sunflower andsugarcane and crops having glyphosate and/or glufosinate tolerance,optionally stacked with auxin tolerance. These compositions can alsoused for controlling undesirable vegetation in crops having glyphosatetolerance optionally stacked with auxin resistance after emergence ofthe crop.

USE EXAMPLES

The effect of the herbicidal compositions according to the invention ofherbicides A and B and, if appropriate, safener on the growth ofundesirable plants compared to the herbicidally active compounds alonewas demonstrated by the following greenhouse experiments:

For the pre-emergence treatment, directly after sowing the activecompounds, which had been suspended or emulsified in water, were appliedby means of finely distributed nozzles. The containers were irrigatedgently to promote germination and growth and subsequently covered withtransparent plastic hoods until plant had rooted. This cover causeduniform germination of the tests plants, unless this was adverselyaffected by active compounds.

For the post-emergence treatment, the test plants were first grown to aheight of 3 to 20 cm, depending on the plant habit, and only thentreated. Here, the herbicidal compositions were suspended or emulsifiedin water as distribution medium and sprayed using finely distributingnozzles.

The respective herbicides B and/or safener were formulated as 10% byweight strength suspension concentrate and introduced to the sprayliquor with the amount of solvent system used for applying the activecompound. Herbicides A, C and/or safener were used as commerciallyavailable formulations and introduced to the spray liquor with theamount of solvent system used for applying the active compound. In theexamples, the solvent used was water.

Glyphosate was used as a commercially available SL-formulationcontaining 360 g/l of glyphosate as its isopropylammonium salt.

Pyroxasulfone was used as an emulsifiable concentrate having an activeingredient concentration of 5% by weight.

Imazamox was used as a commercially available SL-formulation containing120 g/l of imazamox.

Imazapic was used as a commercially available SL-formulation containing120 g/l of imazapic.

Pendimethalin was used as an emulsifiable concentrate having an activeingredient concentration of 396 g/l.

Dimethenamid-P was used as an emulsifiable concentrate having an activeingredient concentration of 720 g/l.

Atrazin was used as an aqueous suspension concentrate having an activeingredient concentration of 500 g/l.

Dicamba was used as a commercially available SL-formulation having anactive ingredient concentration of 480 g/l.

Picolinafen was used as a commercially available WG-formulation havingan active ingredient concentration of 75% by weight.

Saflufenacil was used as an emulsifiable concentrate having an activeingredient concentration of 120 g/l.

Flumioxazin was used as a WG-formulation having an active ingredientconcentration of 51% by weight.

Compound B was used as an emulsifiable concentrate having an activeingredient concentration of 5% by weight.

Compound D was used as an emulsifiable concentrate having an activeingredient concentration of 5% by weight.

Isoxaflutole was used as a WG-formulation having an active ingredientconcentration of 75% by weight.

The test period extended over 21 days. During this time, the plants weretended, and their response to the treatments with active compound wasevaluated.

The evaluation for the damage caused by the chemical compositions wascarried out using a scale from 0 to 100%, compared to the untreatedcontrol plants. Here, 0 means no damage and 100 means completedestruction of the plants.

Colby's formula was applied to determine whether the composition showedsynergistic action. The value E, which is to be expected if the activityof the individual compounds is just additive, was calculated using themethod of S. R. Colby (1967) “Calculating synergistic and antagonisticresponses of herbicide combinations”, Weeds 15, p. 22 ff. For twocomponent mixtures the value E was calculated by the following formula

E=X+Y−(X·Y/100)

For three component mixtures the value E was calculated by the followingformula

E=X+Y+Z−(XY+XZ+YZ)/100+(X·YZ/10000) where X=effect in percent usingherbicide A at an application rate a;

-   -   Y=effect in percent using herbicide B at an application rate b;    -   Z=effect in percent using herbicide C at an application rate c;    -   E=expected effect (in %) of A+B at application rates a+b.        or    -   E=expected effect (in %) of A+B+C at application rates a+b+c.

If the value observed in this manner is higher than the value Ecalculated according to Colby, a synergistic effect is present.
